Resume Writing Tips for System & Network Engineer

Introduction

System and network engineering professionals hold critical roles responsible for designing, maintaining, and optimizing IT infrastructure crucial to business operations. Given the technical nature and high demand for these roles, your resume must clearly highlight your skills, achievements, and the quantifiable impact you’ve created. Recruiters often skim resumes quickly, so it’s vital to present your expertise in a structured, concise, and results-driven manner. This guide shares 10 essential tips to help you write a winning system & network engineer resume that passes Applicant Tracking Systems (ATS) and impresses hiring managers.

1. Resume Summary

The resume summary is your professional elevator pitch—typically 3-4 sentences that capture who you are, your experience, and what you bring to the table. Craft a focused summary that highlights your core competencies, years of experience, and unique contributions, emphasizing system/network engineering expertise.

Example: “Experienced System & Network Engineer with 6+ years managing enterprise-level infrastructure, optimizing network performance, and deploying scalable security solutions. Proven track record in reducing downtime by 30% and improving system efficiency using Cisco and Juniper technologies.”

2. Key Skills

List at least 10 relevant technical and soft skills specific to the system and network engineering domain. This section should align closely with the job description keywords to improve ATS compatibility.

• Network configuration and troubleshooting
• System administration (Linux, Windows Server)
• Firewall and security management
• Cloud infrastructure (AWS, Azure)
• Cisco and Juniper routers/switches
• Virtualization (VMware, Hyper-V)
• Monitoring tools (Nagios, SolarWinds)
• VPN setup and management
• Disaster recovery planning
• Automation using scripting (Python, PowerShell)

3. Achievements vs. Responsibilities

A common resume mistake is listing only job responsibilities instead of achievements. Focus on quantifiable accomplishments that demonstrate your impact rather than generic tasks. Use action verbs and metrics to showcase improvement, efficiency gains, or cost savings.

Example: Instead of “Managed network infrastructure,” write “Reduced network downtime by 25% through proactive monitoring and rapid incident response.”
